EYEGLASS-MOUNTING.

Specification of Letters Patent.

Original application filed. February 17, 1906, Serial No. 301,562. Divided. and this application filed November 6, 1909. Serial No. 526,525. 4

To all whom it may concern Be it known that I, LE F. Apr, of

' Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass- Mountings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the .referencenu- Inerals marked thereon.

The present invention relates to eyeglass mountings and this application is a division of an application-filed by me on-February 17, 1906, Serial No. 301,562.

An object of this invention is to provide .aconstruction in which the springs for positioning finger-piece nose guards are so located as to provide an inconspicuous mounting and have sufficient strength to give the required pressure upon the nose, saidl'springs being separate and readily detachable from the guards and from the mounting independently of the guards and held in place without the provision of separate fastening devices.

A .further object of the invention. is to provide a spring of such a construction and so disposed with reference to the other parts as to offer certain further conveniences in themanipulation of the parts during assembling, adjustment or repair.-

To these and other ends the invention consists. in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is an enlarged plan view of a mounting constructed in accordance with this invention; Fig. 2 is a detail bottom view of the same mounting in proximity to one of the guards; Fig. 3 is a detail vieW,-partly in section,-illustrating the...manner in which a guard is secured to its spring;

the guards; Fig. 5 is a detail perspective view of one of the springs; Flg. 6 is a perspective view of a portion of one of the guards, and Fig. 7' is a transverse sectional- Fig. 4 is a detail perspective- 'iew' of the support in proximity .to one of portion 1, lens attaching devices ,or pore tions 2, and portions 3 at the ends of the bridging portion preferably connecting the latter with the lens attaching devices 2.

Each nose guard preferably comprises a .lever 4 having a nose cngaglng member at its end consisting in this instance of a lower pad 5 and an upper ad '6 formed in one piece with the lever 4, the metal being bent a seat 7 formed by the upper face of one of the connecting portions 3, thus giving stab llty to the guard. Pivotal connectlon .between each guard and the supportis preferably established by the'removable fastener coni'prlsing a pivot portion 8 coiipen ating with the bearing 9 of the lever; screw portion 10 engaging the screw threaded walls 11 of an opening in the portion 3; and a head 12 which coperates with the upper The springs for positioning the guards may each be in the form of a coil 13 preferably made from flat stock into a flat or true spiral form with all its convolut-ions in the same plane. Preferably each coil is mounted below the connecting portion 3 and is unsupported between its ends, so that it does not cooperate with the pivot 4 in any way to interfere with the turning action of its guard. An arm 14 may be extended outwardly from the outer end of the coil in,

rear of the proximate lens attaching device and may be provided wit-h an opening 15 face of the guard lever 4'to firmly hold the same in engagement with the seat 7 alining with an opening 16 in the lens attaching device so that this end of the spring may tfe secured or held in position to react against the supporting structure upon which the guard turns by the fastener 17 that serves to secure the lens to the lens attaching device while the other, end is cooperating with the guard as hereinafter described. The inner end of each coil is preferably detachably secured to the nose guard in order that the latterand the spring'may be subject to independent repair and that the guard may be detached from the mounting without removing the spring, for it will be noted that the support and the springs are located on one side of or below the nose guards. The connection between each guard and its spring is in this instance formed by extending an arm 18 rearwardly from the forward end of the guard toward the pivot and providing the free end of the latter with portions which interlock with the free end of the spring. These portions in this instance are in the form of parallel lugs or cars 19 which form a slot shaped a socket or eye and receive between them the inner end 20 of the spring, and, if desired,

are pressed together so as to bear with friction against the spring end: 20 to prevent accidental displacement but at the same time to permit the arm 18 to be disengaged from the spring end. By extending the arm 18' from the-forward end of the guard lever there is provided a loop at the front end of the guard which serves as a finger piece for the latter and gives an efiicient gripping portion.

In operation, the forward ends of the guard levers are pressed together to separate the nose engaging members at the rear ends. Of course, when the forward ends are released the nose engaging members move toward each other under the action of the the desired pressure of the guards upon the nose and they are so supported that they do not interfere with the pivot bearings of the guards. The guards may be removed with out removing the springs which remain on the mounting so that they are not liable to become mislaid or lost. I

I claim as my invention:

1, The combination with a, support for the lenses comprising a bridging portion, a

lens attaching device and a portion connecting the lens attaching device and the bridging portion, of a nose guard embodying a' lever having pivotal connection with the connecting portion and arranged to one side of the same, and a coil spring on the opposite side of the connecting portion with its axis vertically arranged and having one end secured to the support and its other end detachably acting against the guard.
